Hash Generator

Compute SHA hashes of any text with the Web Crypto API — entirely on your device.

Generate SHA-1, SHA-256, SHA-384, or SHA-512 hashes of any text using your browser's built-in Web Crypto. Fast, private, and nothing is uploaded.

How to use Hash

  1. Type or paste your text.
  2. Pick a hash algorithm (SHA-256 is the common default).
  3. The hash is computed instantly.
  4. Copy the hex digest.

Frequently asked questions

What can I use a hash for?

Hashes verify file or text integrity, create checksums, and fingerprint data. The same input always produces the same hash.

Which algorithm should I choose?

SHA-256 is a solid default for most uses. SHA-384 and SHA-512 produce longer digests; SHA-1 is included for legacy compatibility but is no longer considered secure.

Is my text sent anywhere?

No. Hashing is done locally with the Web Crypto API, so your input never leaves your browser.
